When Seric saw the male protagonist, his emotions fluctuated somewhat.
After all... they had been close friends who shared a bed.
But it was definitely not a positive fluctuation, because he vaguely realized why the male protagonist was here.
When they met again, it was after the protagonist had been abandoned by him. Of course, the male protagonist didn't yet know that he had been abandoned. Instead, he felt somewhat touched.
Because ... Seric had done so much for him, making him feel that Seric was truly good to him, not in a superficial way.
He had originally not liked Seric much, even thinking him somewhat perverse, but now, that dissatisfaction with Seric seemed to dissipate, along with that uncomfortable feeling.
Looking into his eyes, there was no longer any fear, unease, or hatred, just calmness and a "greeting" he felt the other could understand.
